If open file support is configured, Tivoli® Storage Manager performs a snapshot
backup or archive of files that are locked (or "in use") by other
applications.
Use VSS as the snapshot provider; set snapshotproviderimage or snapshotproviderfs to VSS.
Note: - You can use the include.fs option to set snapshot
options on a per file system basis.
- Open file support is only available for local fixed volumes (mounted
to either drive letters or volume mount points) formatted with NTFS
or ReFS file systems. This support includes SAN-attached volumes that
meet these requirements.
- If the client is unable to create a snapshot, failover to non-OFS
backup occurs; the same backup support that would be done if the OFS
feature was not configured.
- To enable open file support in a cluster environment, all systems
in the cluster should have the OFS feature configured.
